In-situ XRD, also known as In situ X-ray Diffraction, is a technique for making X-ray diffraction measurements during a structure or phase transition. This technology can monitor the dynamic change of the structure of the material under external force in real time.

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of not destroying samples and simple operation, and is the main method for the qualitative and quantitative analysis of drug polymorphism at present.

This paper introduces the related knowledge of crystal pattern and crystal fetish

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of no sample destruction and simple operation.

An X-ray diffractometer is a precision instrument used to study the crystal structure, morphology and properties of matter. During the packaging and transportation process, certain measures need to be taken to ensure that the safety and performance of the instrument are not affected.

X-ray diffractometer is mainly used for phase characterization, quantitative analysis, crystal structure analysis, material structure analysis, crystal orientation analysis of powder, block or thin film samples, etc.

Due to the different crystallization conditions, the particles of powder drug samples will have different morphologies.

Polycrystalline X-ray diffractometer, also known as powder diffractometer, is usually used to measure powder, polycrystalline metal or polymer bulk materials.

The full name of XRD is X-ray diffraction, which uses the diffraction phenomenon of X-ray in the crystal to obtain the X-ray signal characteristics after diffraction, and gets the diffraction pattern after processing.

Dandong Tongda Technology Co., LTD., with professional technology and perfect service, has won the trust of scientific research workers around the world.

Petrological studies often require the identification of mineral compositions in rocks, especially those that are less abundant. Therefore, the qualitative analysis of minerals is the most important application of X-ray diffraction in the study of mineral petrology.

Polymers are commonly synthesized as fibers, sheets, and other solid forms. Its properties are greatly affected by its structural parameters such as crystallinity, crystal structure and orientation, and can be studied using XRD
